New product development and old die updating are often encountered in die casting production. In general, the internal and external quality of a die cast is determined by die casting production process parameters such as liquid metal temperature, die casting pressure, speed, and speed switching points. But in most cases, it is also closely related to mold design and manufacturing. Factors that affect the mold include the number of cavities, the design of the pouring system, the type (location and size) of the gate, and the structure of the casting itself. In order to avoid casting defects caused by mold design, and to check and correct some problems in mold manufacturing, so this is what precision die casting mold factories have to say, it is necessary to the finished mold

Precision die casting mold factory introduction: Why die casting mold test

New product development and old mold renewal are often encountered in die casting production. Generally speaking, the internal and external quality of die castings depends on the process parameters of die casting, such as the temperature of molten metal, die casting pressure, speed and speed switching point. But in most cases, it is also closely related to mold design and manufacturing. The factors affecting the mold include the number of cavities, the design of gating system, the type of gate (location and size) and the structure of the casting itself. In order to avoid casting defects caused by mold design, and check and correct some problems in mold manufacturing, this isPrecision die casting die factoryIt is necessary to test the finished die

Die test and process parameter optimization of die casting die

The main purpose of die test is to find out the optimized process parameters and die transformation scheme. It requires that even if the material, machine setting or environment and other factors have changed, the mold can still ensure the stable and uninterrupted batch production of qualified products, and the "adaptability" of the mold can be improved to the greatest extent, not just to obtain several good test modes

1. Find out the problems in the mold

Precision Die Casting Die FactoryAll the dies produced by the factory hope to be a pair of dies with good" adaptability "(that is, wide forming parameters or process conditions). However, due to poor design consideration or improper processing in the manufacturing process, problems such as oversize, unsmooth local transition, and improper structure often occur. The castings are unqualified or the trial production of moulds cannot be carried out. However, mold testing is a simple, direct and effective method to find mold problems

2. Find out the forming conditions

Precision Die Casting Die FactoryDuring die testing, die testers can find the most appropriate set of process data, which can be used as the default value for setting machine parameters during mass production, and adjust the good process conditions for mass production of dies according to this set of data

3. Validate CAE aided design to improve subsequent work efficiency

CAE analysis software is the result of computer simulation and simulation based on the specifications of real machines, the performance of real alloys and the real external environment. According to the simulation, the mold designer makes corresponding modifications to the mold design. When testing a real machine, the analysis data can be directly input as the preset value, so that the tester can check whether the design of the analysis mold is defective. The defects of the test module can be compared with the simulation results to provide a basis for subsequent process parameter settings
